With the rapid development of computer technology and its relative subjects, the Geographic Information Systern (GIS) has developed at very high speed in recent years. Web GIS, a trend of GIS, enable the user conveniently to access to geographic information through Internet. This research develops a high-performance Web GIS based on COM/DCOM to provide map symbol dynamic editing and network publishing through Internet. In order to reduce network traffic and achieve faster response to users, the design of the system considers three major aspects: (1) the architecture of the Web GIS including client, map server, data server and so on; (2) the design and deployment of distributed GIS component; (3) GIS data compression and transferring and its relative key technique. In the end, This work analyses the practical system and draws some conclusions as follow: fast running speed; convenient deployment and maintenance; strong extensibility; strong and flexible editing function for map symbol. In a word, this system can meet the need of different kinds of map symbols dynamic editing for network users.
